1. dylan puts two magnetic toy trains very close to each other on a track. what will happen next, and why?

a the trains will not move because the magnets are not touching.
b the trains will move closer to each other because the magnetic force will pull the trains together.
c the trains will move away from each other because the magnetic force will push the trains apart.
d the trains will move away from each other because the magnets are not touching.

Explanation:

Step1: Recall magnetic force rule

Opposite poles attract, same poles repel.

Step2: Identify poles facing each other

The facing poles are S and S (from the two train magnets).

Step3: Determine force effect

Same poles (S and S) repel, so the trains will move apart.

Answer:

C. The trains will move away from each other because the magnetic force will push the trains apart.
